CHEMICAL HAND FIRE-EXTINGUISHER.

annorrroarrorr forming part or Letters Patent No. 317,152. dated May5,1885.

Application filed March 9,1885. (No model.)

To aZZ whom it may concern..-

Be it known that I, EUGENE H. LEwrs, a

citizen of the United States, residing at Ohioago, county of Cook, andState of Illinois,

have invented certain new and useful Improve ments in'HandFire-Extinguishers, of which the following is a specification.

My invention, which is an improvement upon the one described in mypatent of N ovemher 4, 1884, relates to hand fire-extinguishers withwhich a liquid charged with gases for extinguishing fire is employed.

My invention consists of a cylindrical tube or case, made of tin orother suitable material, provided near the end out of which the liquidis discharged with a partition,which has area sufficient to prevent theliquid from being spilled out of the .tube by any sudden movement inremoving the stopper, but which has apertures enough to permit theliquid in sufficient quantities to be thrown upon a fire to extinguishit. The stopper is fastened or soldered firmly enough to the tube orcase to sustain the weight thereof and its contents, but not so firmlybut that a sudden pull or jerk will easily remove it. p A Wire loop isattached to the stopper, by which the tube and its contents aresuspended from a staple or strong nail driven into the wall. The tube orcase is preferably about twenty inches long and two inches in diameter.When required to be used, the lower portion of the tube is grasped bythe hand, and is given a quick downward movement or jerk, when thestopper is readily removed.

In the accompanying drawings, Figure 1 is a perspective view of a handfire-extinguisher embodying my improvements. Fig. 2 is a perspectiveview of the tube, showing the manner in which it is held suspended by astaple driven into the wall. Fig. 3 is a vertical section of the tube,showing the position of the partition, which is of polygonal shape, andthe manner in which the wire loop is at- 5 tached to the stopper. Fig.dis a top view of the polygonal partition, showing the apertures aroundthe same; and Fig. 5 is a perspective view of the stopper and wire loop,showing the preferable manner of its attachment to the 50 under side ofthe same.

Similar letters refer the drawings.

to similar parts in all A represents the tube, which I prefer to make oftin,and of the size hereinbefore stated.

D is the polygonal partition or diaphragm,

which serves to prevent the liquid from getting out of the tube-in toolarge quantities,and to distribute the contents of the tube over a muchlarger surface. The apertures a a at around the same permit the liquidin suitable quan 6o surface; but the loop may be fastened in any.

otherconvenient and sufficient manner. When required to be used, and thetube A is grasped by the hand and given a quick downward 7o movement,the apertures a a a cause it to give or wrinkle, thus breaking thesolder around the stopper B and causing it to be easily removed.

The stopper B is made of tin, or any other suitable material which willprevent the es h cape of the liquid, and is secured tightly enough tothe tube A by being soldered to support the weight of the tube and itscontents, and, as above stated, it is provided with a wire loop, 0, bymeans of which the extinguisher is suspended from a staple, E, tillrequired for use. When so required, the lower end of the extinguisher isgrasped by the hand and by a quick movement or jerk is drawn from thestopper B, leaving it suspended from the staple E by the wire loop 0.The contents of the tube are sprinkled or showered on the fire, theaction being kept up with vigor,

and any number of tubes used that may be re- 0 quired to entirelyextinguish it.

This hand-extinguisher is designed for smaller or incipient fires. Theliquid used is such that by its contact with a heat of about 150Fahrenheit gases are generated which extinguish fire by absorbing theoxygen.

The essential feature of my invention is the making of a handfire-extinguisher,with which a liquid charged with gases is employed,consisting of a tube closed at both ends and pro- Ico vided with apartition of polygonal shape ;v and it being apparent that suchextinguisher maybe used without employing all the special features abovementioned-as, for instance,
